John Audia d6a9a92e32 kernel: bump 5.4 to 5.4.69
Seemingly unneeded based on new upstream code so manually deleted:
 layerscape:
  820-usb-0007-usb-dwc3-gadget-increase-timeout-value-for-send-ep-c.patch

Manually merged:
 generic-hack:
  251-sound_kconfig.patch

All other modifications made by update_kernel.sh

Build system: x86_64
Build-tested: ipq806x/R7800, ath79/generic, bcm27xx/bcm2711
Run-tested: ipq806x/R7800, lantiq/Easybox 904 xDSL

No dmesg regressions, everything functional

Subject: [PATCH] drm/vc4: Enable audio on Pi4.
This could be a revert of "drm/vc4: hdmi: Add an audio support flag"
as it is no longer needed.
